CROSS-REFERENCE TO RELATED APPLICATION

This application claims priority from and the benefit of Korean Patent Application No. 10-2014-0041887, filed on Apr. 8, 2014, the entirety of which is hereby incorporated by reference for all purposes as if fully set forth herein.

BACKGROUND

1. Field

Example embodiments relate to machine translation technologies for generating a translation of a source sentence using a computer.

2. Description of the Background

With the recent increasing exchange of communication between nations, and development and expansion of an information technology (IT), the use of machine translation apparatuses for translating a sentence of a first language (e.g., a source language) to a sentence of a second language (e.g., a target language) is increasing. Generally, the machine translation apparatuses translate an input source sentence of one language to a sentence of another language through operations, which includes such as a morpheme analysis, a syntactic analysis, a conversion operation, and/or a generation operation, with respect to the input source sentence.

Machine translation methods according to the related art may include, for example, a direct method, a transfer method, and a pivot method based on an analysis level of a sentence. The direct method translates a sentence based on a direct correspondence between a source language and a target language, the transfer method translates a sentence through an operation of defining two intermediate expressions and performing an analysis, a conversion, and a generation operation with respect to each of the source language and the target language, and the pivot method translates a sentence through an analysis operation and a generation operation by defining a single neutral expression with respect to the source language and the target language.

Meanwhile, machine translation methods developed during the 1990s include, for example, a rule-based machine translation, a statistics-based machine translation, and a hybrid machine translation in which the rule-based machine translation and the statistics-based machine translation are combined. The machine translation methods may perform a translation based on knowledge or translation examples obtained from a previous translation process or statistics.

For example, Korean Laid-Open Publication No. 10-2010-0037813, published on Apr. 12, 2010, discloses a machine translation apparatus and method based on a statistical method that applies linguistic information to a statistical machine translation based on an analysis about a bilingual parallel corpus.

FIG. 1 illustrates an example of a probabilistic machine translation candidate according to a related art. Referring to FIG. 1, a probabilistic machine translation according to the related art generates a translation by measuring scores based on a word/sentence/rule of a translation candidate with respect to a source sentence, by combining corresponding candidates, and by sorting total scores of a sentence.

FIG. 2 illustrates an example of finding a correct path of translating a source sentence in German to a target sentence in English according to a related art. Referring to FIG. 2, corresponding candidates may be sorted and then displayed in descending order of probabilities.

As described above, the machine translation technology according to the related art generally considers information only regarding whether a translation of a source sentence is correct.

DETAILED DESCRIPTION

Various example embodiments are described more fully hereinafter with reference to the accompanying drawings, in which the example embodiments are shown. Example embodiments may, however, be embodied in many different forms and should not be construed as limited to the example embodiments set forth herein. Rather, these example embodiments are provided so that this disclosure is thorough, and will fully convey the scope of example embodiments to those skilled in the art. In the drawings, the size and relative sizes of layers and areas may be exaggerated for clarity. Like reference numerals in the drawings denote like elements, and thus their description will be omitted.

It will be understood that when an element is referred to as being “connected” or “coupled” to another element, it can be directly connected or coupled to the other element or intervening elements may be present. In contrast, when an element is referred to as being “directly connected” or “directly coupled” to another element, there are no intervening elements present. As used herein the term “and/or” includes any and all combinations of one or more of the associated listed items. Other words used to describe the relationship between elements or layers should be interpreted in a like fashion (e.g., “between” versus “directly between,” “adjacent” versus “directly adjacent,” “on” versus “directly on”).

It will be understood that, although the terms “first”, “second”, etc. may be used herein to describe various elements, components, areas, layers and/or sections, these elements, components, areas, layers and/or sections should not be limited by these terms. These terms are only used to distinguish one element, component, area, layer or section from another element, component, area, layer or section. Thus, a first element, component, area, layer or section discussed below could be termed a second element, component, area, layer or section without departing from the teachings of example embodiments.

Spatially relative terms, such as “beneath,” “below,” “lower,” “above,” “upper” and the like, may be used herein for ease of description to describe one element or feature's relationship to another element(s) or feature(s) as illustrated in the figures. It will be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as “below” or “beneath” other elements or features would then be oriented “above” the other elements or features. Thus, the example term “below” can encompass both an orientation of above and below. The device may be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of example embodiments. As used herein, the singular forms “a,” “an” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that the terms “comprises” and/or “comprising,” when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof. Expressions such as “at least one of,” when preceding a list of elements, modify the entire list of elements and do not modify the individual elements of the list.

Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which example embodiments belong. It will be further understood that terms, such as those defined in commonly-used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the relevant art and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein.

Hereinafter, example embodiments will be described with reference to the accompanying drawings.

The example embodiments relate to machine translation technologies for automatically generating a translation of a source sentence using a computer.

FIG. 3 is a diagram illustrating a relationship between a user terminal and a machine translation system according to an example embodiment. FIG. 3 illustrates a user terminal 301 and a machine translation system 300. In FIG. 3, an indicator with a double arrow indicates that data may be transmitted and received between the user terminal 301 and the machine translation system 300 over a wired/wireless network.

The machine translation system 300 serves as a translation engine to translate a sentence of a source language (hereinafter, a source sentence) input from a user to candidate sentences of a target language (hereinafter, a translation), and to provide a translation result. In particular, the machine translation system 300 may provide the translation result by sorting candidate translation sentences with respect to the source sentence in order of scores, by extracting one or more candidate translation sentences (e.g., N candidate translation sentences), and by classifying the extracted candidate translation sentences based on a semantic category.

The user terminal 301 may refer to any type of terminal devices capable of connecting to a website/mobile site associated with the machine translation system 300. For example, the machine translation system 300 may include a personal computer (PC), a smartphone, a tablet, a laptop computer, a digital multimedia broadcasting (DMB) terminal, a portable multimedia player (PMP), and a navigation terminal, or installing and executing a service exclusive application. The user terminal 301 may perform the overall service operation (e.g., configuring a service screen, receiving data, performing a data transmission and reception, and/or storing data) under the control of the website/mobile site or the service exclusive application. The user terminal 102 may refer to any type of terminal devices, for example, a personal computer (PC), a smartphone, and a tablet, to input a source sentence to the machine translation system 300 and to output a translation result provided from the machine translation system 300. The user terminal 301 may include an input device to input the source sentence to the machine translation system 300 and an output device to output the translation result provided from the machine translation system 300. For example, the input device may be a keyboard, a mouse, a scanner, and a microphone, and the output device may be a monitor, a printer, and a speaker.

FIG. 4 is a block diagram illustrating a configuration of a machine translation system according to an example embodiment. Referring to FIG. 4, the machine translation system may include a processor 400 including a translation generator 410 and a result provider 420, a memory 401, and a network interface 402. The processor 400, according to a control of at least one program stored, for instance, in the memory 401 may be configured to perform processes including generating candidate sentences by translating a source sentence of a source language into a target language, classifying the candidate sentences into semantic categories, respectively, and providing at least one of the classified candidate sentences as a translation result. The machine translation system may include a database system associated with various translation models to automatically generate a translation from a source sentence. For example, the translation models for a machine translation may use a rule-based machine translation model 403, a statistics-based machine translation model 404, and a hybrid machine translation model 405 in which a rule-based method and a statistics-based method are combined.

The memory 401 may store a program including an instruction corresponding to a machine translation routine of generating a candidate translation sentence with respect to a source sentence, and classifying the candidate translation sentence into a corresponding semantic category. Processes performed by the machine translation system may be executed by the program stored in the memory 401. For example, the memory 401 may be a hard disk, a solid state disk (SSD), a secure digital (SD) card, and other storage media.

The network interface 402 may combine a network with the machine translation system for communication with user terminals using a semantic category-based machine translation service.

The processor 400 refers to an apparatus configured to perform processing in response to an instruction of the program stored in the memory 401, and may include a microprocessor such as a central processing unit (CPU). Hereinafter, a detailed configuration of the processor 400 will be described.

The translation generator 410 may generate a translation by applying, to the source sentence, a desired (or alternatively, predefined) machine translation model, for example, the rule-based machine translation model 403, the statistics-based machine translation model 404, and the hybrid machine translation model 405. For example, the translation generator 410 may generate candidate translation sentences as sentences of various semantic categories during a process of generating a translation of the source sentence. That is, the translation generator 410 may sort candidate sentences that are translated from a source sentence in order of scores, extract N candidate translation sentences, and classify the extracted candidate translation sentences into a corresponding semantic category. Here, the term “semantic category” may indicate all the criteria for classifying attributes of a sentence, which includes a writing style, a sentence structure, a tense, and/or a linguistic norm. For example, the semantic category may be classified into a literary style and a colloquial style based on the writing style, may be classified into a declarative sentence, a pleasant sentence, an imperative sentence, a honorific form, and a plain form based on the sentence structure, and may be classified into a past tense, a present tense, and a future tense based on the tense, and may be classified into a standard language and a dialect based on the linguistic norm.

The result provider 420 may provide a translation of the source sentence. For example, the result provider 420 may provide a translation result by including candidate translation sentences having similar meanings to each other. Here, providing candidate translation sentences refers to providing the candidate translation sentences in a complete sentence form instead of simply providing word candidates having similar meanings to each other. Thus, the candidate translation sentences may include, for example, a complete sentence in which words are replaced with other words having similar meanings and a complete sentence in which a word and a structure are differently configured. As an example of providing a translation result, the result provider 420 may classify and display candidate translation sentences with respect to respective semantic categories. As another example of providing a translation result, the result provider 420 may select and display candidate translation sentences classified based on a purpose of a user (e.g., a semantic category selected by the user). As still another example of providing a translation result, the result provider 420 may select and display candidate translation sentences classified into semantic categories suitable for an personality of a user. For example, the personality of the user may be analyzed from user information accumulated on the Internet. For example, a semantic category of a sentence predicted to be used by the user may be induced by analyzing a service type or a writing style frequently used by the user. As yet another example, the result provider 420 may select and display, from among candidate translation sentences of a source sentence, a sentence having a semantic category identical to the semantic category of the source sentence by automatically classifying the semantic category of the source sentence input from the user.

According to the above configuration, as expressed by Table 1, the machine translation system according to some example embodiments may provide sentences suitable for each semantic classification by generating or performing post-processing of the sentence, during a process of generating candidate translation sentences. In Tables 1 and 2, and throughout the specification, unless defined otherwise, the source sentence is written in English and translations are written in Korean.

TABLE 1 Source sentence I just looking around. Translations (1) literary/honorific/present/formal/article:

. (2) literary/plain/past/novel:

. (3)colloquial/honorific/will/future/conversation translation:

. (4) colloquial/plain/present/conversation:

. (5) colloquial/honorific/present/intimate/conversation:

. (6) colloquial/contracted (SNS style)/plain/will/future:

Accordingly, during a process of generating candidate translation sentences of a machine translation, the machine translation system may classify the candidate translation sentences based on semantic categories and accordingly, may provide a translation suitable for the purpose or the personality of the user. For example, the machine translation system may generate translations of various semantic categories, for example, a literary sentence in a form of an article with respect to a source sentence of a news article and a colloquial sentence suitable for a conversion on an SNS (e.g., a messenger and a bulletin board).

Hereinafter, a semantic categorization method according to a configuration of a machine translation will be described in detail.

Rule-Based Machine Translation Model

A general rule-based machine translation method may generate a translation rule based on language information of a source language and a target language, and may generate a translation with respect to a source sentence based on the translation rule.

TABLE 2 Source sentence (input sentence) I drunk a cup of water. Translation

.

Hereinafter, a rule-based translation generating process will be described with reference to an example of Table 2:

1. Generalization: [subject] [verb past tense] [object1] [object2].

2. Change of order: [subject] [object2] [object1] [verb past tense]

3. Apply characteristics of language: [subject] (

) [object2] (

) [object1] [verb past tense]

4. Apply translation rule: [

]

[

] [

]

[

].

Accordingly, the machine translation system may generate a rule for each of various semantic categories and may generate a translation suitable for each semantic category. That is, the machine translation system may add translation rules corresponding to respective semantic categories to a translation rule of a general rule-based machine translation method.

Referring to Table 2, a translation rule corresponding to a semantic category may be applied to an inflection or may be applicable to the entire sentence. As a result, the following examples may be acquired:

Examples

Future tense rule:

(corresponding to “I will drink a cup of water”).

Colloquial style rule:

(corresponding to “I'm drinking a cup of water”).

Conversation style rule:

(corresponding to “I'm drinking water”).

Contracted rule:

(corresponding to “drinking water”).

A plurality of candidate sentences may be generated by applying a translation rule corresponding to each semantic category. Each of the generated candidate sentences may be classified into an appropriate semantic category.

Examples

.→classified into a future tense.

.→classified into a colloquial style.

→classified into a conversion style.

→classified into a contracted style.

Candidate translation sentences may be classified using a statistical method or a regular method.

The statistical method for classifying sentences refers to a method of statistically estimating meanings of sentences and classifying the sentences. For example, “d classifyicorresponding to “I ate a meal”)” may be estimated to be probabilistically close to a literary style, and ““or exampcorresponding to “ate a meal”)” may be estimated to be probabilistically close to a colloquial style.

The regular method for classifying sentences refers to a method of determining a semantic category of a sentence by semantically analyzing constituent elements of the sentence and then applying a corresponding rule. For example, the regular method may be expanded from a simple rule of classifying a sentence ending with “˜ith to a colloquial style and classifying a sentence ending with “˜th into a literary style, to various rules having a higher complexity.

Statistics-Based Machine Translation Model

A general statistics-based machine translation method may include a translation model constructing process, a language model constructing process, and a translation selecting process using a translation model and a language model.

A machine translation system may construct a translation probability table using translation pair data of different two languages, which are the subject languages for translation.

FIG. 5 illustrates a translation probability table constructing process for a statistics-based machine translation according to an example embodiment. As an example, referring to FIG. 5, a machine translation system may receive large translation pair data of two languages in operation 501, may estimate a translation probability between words from the large translation pair data in operation 502, and may determine a phrase section based on the estimated translation probability between words in operation 503. The machine translation system may generate candidate phrase data with respect to the determined phrase section in operation 504, may extract a phrase from the candidate phrase data in operation 505, and may construct a translation model including a translation probability table in operation 506.

The machine translation system may construct a probability list about a naturalness of a sentence by constructing a language model for each language based on large data of a corresponding language.

FIG. 6 illustrates a language model constructing process for a statistics-based machine translation according to an example embodiment. As an example, referring to FIG. 6, a machine translation system may receive large data of a sentence written in a language in operation 601, may estimate and store a probability of a corresponding word string from the large data in operation 602, and may construct a language model indicating a probability list about a naturalness of a sentence in operation 603.

Next, the machine translation system may select a translation using a bilingual translation model and a monolingual language model.

FIG. 7 is a diagram describing a translation selecting process using a translation model and a language model according to an example embodiment. As an example, referring to FIG. 7, a machine translation system may select an optimal candidate sentence from among a plurality of candidate translation sentences with respect to a source sentence using a translation model constructed from a bilingual corpus and a language model constructed from a monolingual corpus, through a decoder 703. FIG. 8 illustrates a process of selecting a translation in English with respect to a source sentence in German. Referring to FIG. 8, a merged sentence of shadowed columns indicates a sentence string of which a phrase probability in the translation model and a word string in the language model are simultaneously high.

The aforementioned statistics-based machine translation method may be applied to the candidate sentence generation technology proposed herein.

As an example, the machine translation system may sort candidate sentences translated from a source sentence in order of scores by applying a translation selecting method of a statistics-based machine translation and may extract N candidate sentences in descending order of scores. The machine translation system may classify the extracted N candidate sentences into appropriate semantic categories. Thus, a candidate sentence may be classified into an appropriate semantic category using the statistical method or the regular method.

Accordingly, the machine translation system may translate a source sentence to be probabilistically suitable for a semantic category by constructing language models suitable for respective semantic categories and by applying the constructed language models to a machine translation. The language models constructed with respect to respective semantic categories and applied to the machine translation function to generate a probabilistically natural sentence through a corpus including a large sentence. In this instance, the machine translation system may estimate a probability of a specific semantic category by selectively constructing a language model to be suitable for the specific semantic category. For example, once a probability table is generated by constructing a large corpus of twitter, a sentence of a twitter style is highly likely to be selected.

Hybrid Machine Translation Model

A general hybrid machine translation method refers to a method of appropriately applying the aforementioned rule-based machine translation method and statistics-based machine translation method. Similarly, the hybrid machine translation method may generate a plurality of candidate translation sentences with respect to a source sentence and may classify the candidate translation sentences into appropriate semantic categories, respectively.

In the machine translation method, a hybrid method of a rule-based method and a statistics-based method may be enabled. Accordingly, a method of selecting a candidate translation sentence based on a semantic category may also employ the hybrid method of the rule-based method and the statistics-based method.

For example, a machine translation system capable of performing a hybrid method (e.g., a combination of a rule-based method and a statistics-based method) may generate a plurality of candidate translation sentences based on various semantic categories during a process of generating a translation of a source sentence.

The machine translation system may provide a translation of a source sentence by including, in a translation result, a plurality of candidate sentences having the same or similar meanings. As an example, the machine translation system may sort a plurality of candidate sentences translated from a source sentence in order of scores, may extract N candidate sentences, and may display a translation result so that an optimal sentence having the highest scores may be distinguished from other candidate sentences. Further, the machine translation system may provide other candidate sentences in a complete sentence form by including the other candidate sentences in the translation result.

FIG. 9 illustrates an example of a translation result screen 900 for translating Korean to English according to an example embodiment. A machine translation system may display translations 920 and 930 translated in English as a translation result, in response to a source sentence “

” 910 to Korean. Here, as a translation result for the source sentence “

” 910, the machine translation system may classify and display the translation 920 corresponding to an optimal sentence (e.g., “That's all right” having the highest scores) and the translations 930 corresponding to candidate sentences (e.g., “No problem”, “Never mind”, and “It doesn't matter”) having same or similar meanings to “That's all right”.

FIG. 10 illustrates an example of a translation result screen 1000 for translating English to Korean according to an example embodiment. A machine translation system may display translations 1020 and 1030 translated in Korean as a translation result, in response to a source sentence “I'm just looking around.” 1010 in English. Here, as a translation result for the source sentence “I'm just looking around” 1010, the machine translation system may classify and thereby display the translation 1020 corresponding to an optimal sentence (e.g., “

” having the highest scores) and the translations 1030 corresponding to candidate sentences (e.g., “

”, “

”, “

”, and the like), which have same or similar meanings to “

”

In particular, the machine translation system may classify and display sentences included in the translation result for respective semantic categories. For example, the semantic categories may indicate criteria for classifying attributes of the sentences, such as a writing style (e.g., a literary style and a colloquial style), a sentence structure (e.g., a declarative sentence, a pleasant sentence, an imperative sentence, a honorific form, and a plain form), a tense (e.g., a past tense, a present tense, and a future tense), and a linguistic norm (e.g., a standard language and a dialect). As an example, referring to FIG. 11, the machine translation system may display corresponding semantic categories 1140 to be adjacent to sentences 1120 and 1130 included in the translation result.

As another example, the machine translation system may display a candidate sentence suitable for a semantic category selected by a user as a translation result. For example, the machine translation system may display only a specific candidate sentence corresponding to a specific semantic category selected by the user, among a plurality of candidate sentences or may display the plurality of candidate sentences in a way that the specific candidate sentence corresponding to the specific semantic category selected by the user may be distinguished from among the plurality of candidate sentences. For example, referring to FIG. 12, a menu environment 1250 capable of designating a semantic category of a translation that the user desires to receive may be displayed at a desired (or alternatively, predetermined) location of a translation result screen 1200. Accordingly, the machine translation system may receive a selection of a user on a semantic category through the menu environment 1250 and then may select and display a specific candidate sentence classified into the selected semantic category. Further, the machine translation system may be configured to include a semantic category selecting path, which may be provided by setting an environment of a translator such that a pop-up button or window is displayed to request or prompt a selection of a semantic category in response to an input of a source sentence or such that a specific category is pre-set.

Further, although a user does not select a desired (or alternatively, predetermined) semantic category every time, the machine translation system may predict and automatically set a semantic category of a translation that the user is highly likely to desire to receive, based on information regarding a personality of the user. For example, the personality of the user may be analyzable based on user information on the Internet. For example, a semantic category of a sentence suitable for the personality of the user may be set by analyzing, for example, news articles, internet cafes, web blogs, and/or messengers, frequently used by the user, or a writing style frequently used by the user. That is, a sentence inclination of the user may be automatically applied when displaying a translation result by analyzing a sentence inclination frequently used by the user.

Also, when a source sentence is input from a user, the machine translation system may automatically classify a semantic category of the source sentence based on a writing style or a sentence structure of the source sentence, and may display a candidate sentence of which a semantic category is the same as or similar to the semantic category of the source sentence, among candidate sentences translated from the source sentence, to be distinguished from other candidate sentences. For example, when a semantic category of a source sentence is classified into a colloquial style and a honorific form, a sentence of which a writhing style and a sentence structure are classified into a colloquial style and a honorific form, may be displayed as a translation result among candidate sentences translated from the source sentence.

The aforementioned machine translation method may include at least two operations (e.g., one operation associated with a bilingual translation model and another operation associated with a monolingual language model) based on a detailed description of the machine translation system described above with reference to FIGS. 3 through 12.

The methods according to example embodiments may be recorded in non-transitory computer-readable media in a form of a program instruction executable through various computer systems.

A program associated with an input of a source sentence and an output of a translation in the machine translation method according to the example embodiments may be configured as a PC-based program or an application exclusive for a mobile terminal. A machine translation application (App) according to the example embodiments may be configured as an independently operating program or an in-app form of a desired (or alternatively, predetermined) application, for example, a search program to be operable on the desired (or alternatively, predetermined) application.

Also, the methods according to the example embodiments may be performed in such a manner that an application associated with a server system to provide a translation service controls a user terminal. As an example, the application may include a module configured to receive, from a user, a source sentence or a selection on a semantic category of a translation that the user desires to receive, and to transfer the received source sentence or semantic category to a server system, and a module configured to output a translation received from the server system. Also, the application may be installed in the user terminal through a file provided from a file distribution system. As an example, the file distribution system may include a file transmitter (not shown) configured to transmit the file in response to a request of the user terminal.

As described above, according to example embodiments, it is possible to provide a candidate sentence to substitute a translation of a source sentence as a sentence in a complete form, to classify and display a candidate translation sentence included in a translation result based on a semantic category, and particularly, to select and provide a translation of a semantic category suitable for the purpose or personality of a user.
